Calibrachoa plant named ‘INTA 06575’

ABSTRACT

A new and distinct  Calibrachoa  plant named ‘INTA 06575’, characterized by its compact, upright to outwardly spreading and mounding to eventually trailing plant habit; vigorous growth habit; freely branching habit; dense and bushy appearance; early and freely flowering habit; purple-colored flowers with yellow-colored throats; and good garden performance.

Botanical designation: Calibrachoa caesia×Calibrachoa hybrida.

Cultivar denomination: ‘INTA 06575’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa caesia×Calibrachoa hybrida and hereinafter referred to by the name ‘INTA 06575’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventors in Hurlingham, Province of Buenos Aires, Argentina. The objective of the breeding program is to create new vigorous and freely-flowering Calibrachoa plants with unique and attractive flower coloration and good garden and summer performance.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventors in Hurlingham, Province of Buenos Aires, Argentina in September, 2005 of a proprietary selection of Calibrachoa caesia identified as code number 2003092512, not patented, as the female, or seed, parent with the proprietary selection of Calibrachoa hybrida referred to as ‘Dark Blue’, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Hurlingham, Province of Buenos Aires, Argentina in October, 2006.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Hurlingham, Province of Buenos Aires, Argentina since October, 2006 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘INTA 06575’. These characteristics in combination distinguish ‘INTA 06575’ as a new and distinct Calibrachoa plant:

-   -   1. Compact, upright to outwardly spreading and mounding to         eventually trailing plant habit.     -   2. Vigorous growth habit.     -   3 Freely branching habit; dense and bushy appearance.     -   4. Early and freely flowering habit.     -   5. Purple-colored flowers with yellow-colored throats.     -   6. Good garden performance.

The new Calibrachoa plant can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more outwardly spreading         than and not as upright as plants of the female parent         selection.     -   2. Plants of the new Calibrachoa have smaller leaves than plants         of the female parent selection.     -   3. Plants of the new Calibrachoa have larger flowers than plants         of the female parent selection.

The new Calibrachoa plant can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are taller than plants of the         male parent selection.     -   2. Plants of the new Calibrachoa have longer internodes than         plants of the male parent selection.     -   3. Plants of the new Calibrachoa and the male parent selection         differ slightly in flower color as plants of the male parent         selection have purple violet-colored flowers.     -   4. Plants of the new Calibrachoa have better garden performance         than plants of the male parent selection.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa sp. ‘USCALI11’, disclosed in U.S. Plant Pat. No. 14,968. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘USCALI11’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa were shorter than plants of         ‘USCALI11’.     -   2. Plants of the new Calibrachoa were more vigorous than plants         of ‘USCALI11’.     -   3. Plants of the new Calibrachoa had smaller flowers than plants         of ‘USCALI11’.     -   4. Plants of the new Calibrachoa and ‘USCALI11’ differed in         flower color as plants of ‘USCALI11’ had light red         purple-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa sp. ‘Caltrapi’, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘Caltrapi’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa were more mounding than and not         as flat as plants of ‘Caltrapi’.     -   2. Plants of the new Calibrachoa were more vigorous than plants         of ‘Caltrapi’.     -   3. Plants of the new Calibrachoa had smaller flowers than plants         of ‘Caltrapi’.
